摘要

The invention seeks for the Oromo solution of zolpidem or the acceptable salts on the medicine thereof. The present invention refers to the oral or subabdominal formulation of zolpidan, or zolpidan salt that can be accepted as a drug. The formulation minimizes the number of penetration enhancers, but provides rapid drug penetration across adhesives. These formulations not only provide the ideal concentration (0.5-10% w) of the drug in the form of transparent (clear) solutions,They are also able to achieve a stable formulation over the entire life span of at least 2 years. The pH value range of the stable non-aqueous solution of the invention is pH 5-9, preferably 6-9 and 7-9.
